结局指标

主要结局

Sustained Maximal Inspiratory Pressure (SMIP)

时间窗: Week 12

SMIP measured in pressure-time units (PTU) will be assessed using the Pro2 handheld inspiratory measurement and training device connected to a tablet, phone or desktop.

Root Mean Squared of Successive Differences between Normal Heartbeats (rMSSD)

时间窗: Week 12

rMSSD, measured in milliseconds, will be derived from signals obtained by a Polar monitor (with elastic chest strap sensor) and analyzed using Kubios Heart Rate Variability (HRV) Analysis Software.

Functional Seated Balance

时间窗: Week 12

Functional Seated Balance will be measured using the Function in Sitting Test for SCI (FIST-SCI). FIST-SCI consist of 14 different standardized seated balance tasks and scored on a 5-point ordinal scale from 0-4. A higher score indicates increased independence.

Quality of Life (QoL)

时间窗: Week 12

QoL will be measured using the Quality of Life Index, SCI version (QOLI-SCI). QOLI-SCI is a set of two 37-items questionnaire with total scores ranging from 74 to 444 with the higher score indicating increased quality of life.

Independence

时间窗: Week 12

Independence will be measured using the Spinal Cord Independence Measured (SCIM). SCIM has a total score ranging from 0-100 with the higher score indicating increased independence.

Percent Compliance of Training Sessions

时间窗: 4 weeks

Feasibility of the IMT protocol will be reported as the percentage of completed daily sessions out of the 28 total session days.

Percent Compliance of Training Minutes

时间窗: 4 weeks

Feasibility of the IMT protocol will also be reported as the percentage of completed total time out of the 840 minutes total expected session minutes(30 minutes daily for 28 days).

Maximal Inspiratory Pressure (MIP)

时间窗: Week 12

MIP measured in cm H2O will be assessed using the Pro2 handheld inspiratory measurement and training device connected to a tablet, phone or desktop

Standard deviation of normal R-R intervals (SDNN)

时间窗: Week 12

SDNN, measured in milliseconds, will be derived from signals obtained by a Polar monitor (with elastic chest strap sensor) and analyzed using Kubios Heart Rate Variability (HRV) Analysis Software.

Systolic Blood Pressure (SBP)

时间窗: Week 12

Brachial systolic BP, evaluated in mmHg, will be evaluated using the contralateral arm with a Spot Vitals Monitor.

次要结局

  • Maximal Expiratory Pressure (MEP)(Week 12)
  • Inspiratory Duration (ID)(Week 12)
  • Forced Vital Capacity(Week 12)
  • Forced Expiratory Volume in one Second (FEV1)(Week 12)
  • Peak Expiratory Flow (PEF)(Week 12)
  • Heart Rate Variability (HRV) Frequency(Week 12)
  • Diastolic Blood Pressure (DBP)(Week 12)
